indexТип: IntegerA zero-based integer indicating which element to retrieve.

The .get()
method grants access to the DOM nodes underlying each jQuery object. If the value of index
is out of bounds — less than the negative number of elements or equal to or greater than the number of elements — it returns undefined
. Consider a simple unordered list:
1
2
3
4
|
|
With an index specified, .get( index )
retrieves a single element:
1
|
|
Since the index is zero-based, the first list item is returned:
<li id="foo">
Each jQuery object also masquerades as an array, so we can use the array dereferencing operator to get at the list item instead:
1
|
|
However, this syntax lacks some of the additional capabilities of .get(), such as specifying a negative index:
1
|
|
A negative index is counted from the end of the matched set, so this example returns the last item in the list:
<li id="bar">

Without a parameter, .get()
returns an array of all of the elements:
1

All of the matched DOM nodes are returned by this call, contained in a standard array:
[<li id="foo">, <li id="bar">]
